"THE" fail safe electric actuator
For all quarter turn applications, Spring Return
FQ range Actuators ensure automatic opening
or closing even without any power supply.
■ APPLICATION FIELDS
They include :
● All those where the loss of power supply
necessitates automatically to put the driven
device in a safety position.
● All those where the risks are such, that driving
the device to its safety position must
be possible at any time even in the absence
of power supply.
For example : Storage and distribution of gas
and dangerous fluids, fire protection systems,
chemical installation safety, climate control
and ventilation of hazardous areas (protection
of the environment).
■ IMPORTANT FUNCTIONS
When energized (after electrical wiring) the
actuator operates the valve normally and at
the same time compresses the spring which is
held in the loaded position by the solenoid
brake. In case of power failure to the solenoid,
the spring will drive the actuator and valve to
the safety position either open or closed. The
associated dashpot speed controls the spring
action and permits a safe and shock-free operation
of the valve. When the power supply is
restored (no resetting of the spring is
required), the actuator is immediately available
for normal operation.
In standard, the spring operates clockwise
when viewed from the top. The electric part is
equipped with an asynchrone triphase motor
of squirrel cage type. Other versions are possible
in single phase and direct current supply.
What is FAIL SAFE ?
In addition to their normal function of on-off or
modulating actuators, FQ operators are
designed in order to immediately close or
open the driven device, thanks to the action
of an integrated spring, and without any
external power source, whenever they detect
an emergency such as :
■ A loss of signal,
■ An abnormal temperature,
■ Or the loss of power itself.
■ STANDARD DESIGN
● Mechanical position indicator
● Travel limit switch setting is easy, with a
simple screw driver
● Adjustable mechanical stops for quarter
turn
● Electrical connection to a terminal strip.
■ ENCLOSURES
